Rind is smooth with a fairly uniform color, developing a deep red blush at maturity. Internal flesh color is red, it has very few seeds and flavor is very sweet. Star Ruby matures from mid-April to mid-May in suitable areas. The fruit maintains its quality on the tree until mid-June.

This variety has good internal quality as well as good rind pigmentation. It is a pink grapefruit that can be recognized externally without having to be cut open. Except for the color, Ruby is virtually identical to Marsh in most fruit characteristics. Additionally, it usually has very few seeds. Ruby Red is the most widely grown pigmented variety worldwide and is likely to remain so for some considerable time due to its increasing demand.
